In magnetic physics, this term is used to describe a magnet with frustrated interactions in which ferromagnetic and antiferromagnetic states are distributed randomly. In addition to describing that kind of "glass," this word names a number that can be found for an arbitrary direction z by multiplying m-sub-s by the reduced Planck constant. This word also names a property whose interaction with orbital effects gives rise to fine structure splitting. This word names a quantized property of particles that was first discovered in the Stern-Gerlach experiment. For 10 points, identify this word that names the intrinsic angular momentum of particles, such as half-integer values for fermions.
